As the tomato ripens, its colour starts to change from GREEN to yellow and then eventually to red. This is due to the breakdown of chlorophyll, which in TURN SYNTHESISES a red carotenoid (another pigment group), lycopene. When ripe, the carotenoid can easily be seen as the DOMINANT colour of thetomato, ie red

GIVE PROPER QUESTIONS

You can substitute BAKING soda for baking powder, if you increase the AMOUNT of acidic ingredients in the RECIPE to offset the baking soda. You'll also need much less baking soda as it is 3 times as powerful as baking powder. You'll need about a TEASPOON of vinegar or lemon juice for EVERY 1/2 teaspoon of baking soda.

The motion of an object shows its CHANGING position, as discussed EARLIER. But varying objects show varying TYPES of motion. Like for example, a fan is said to be in motion though it is static in its PLACE or a hanging clock that shows motion though it is hanging in its position. We say that motion is mainly of THREE types: Rectilinear Motion, Circular Motion and Periodic Motion.

Motion and measurement

Rectilinear Motion

In a rectilinear motion, all the objects move along a single line. Some common examples of rectilinear motion are marching soldiers, moving cars, and moving animals. The common thing in all these examples is that they move in a single line.

Circular Motion

have you noticed the motion of a fan? Some objects are moving even though they are fixed at some position. here the fan undergoes circular motion. In the circular motion, the objects follow a circular path of motion without changing their position. It is the circular movement of fan that results in cool air. Some more examples of circular motion are the motion of a Ferry wheel, satellites and rotation of planets around the sun.

Periodic Motion

Have you ever seen a clock’s pendulum? It repeats its movement after a specific time. Physically the pendulum isn’t moving. It is fixed to some point, yet it shows motion. This kind of motion that repeats after a specific period of time is known as periodic motion. In the periodic motion, the movement made by these objects is called oscillation.

Since it repeats after a fixed period of time, it is named so!  Clocks and table fans are the most common examples. Some other examples of the periodic motion are a child’s motion on swings, the motion of the earth around the Sun, the motion of the moon around the earth.

The world around us is moving. Everything that we see is showing some kind of motion. Can you now chalk out a few examples that show all or at least more than one type of motion?

This MOTION is PERIODIC motion

<U>ANSWER:-

500 km in 20 seconds

500000 m in 20 seconds

1 m in 20/500000

90 m in 20/500000 * 90 = 0.0036 seconds

hope it helps u in anyway and if it does then plz mark it as brainliest

Before you PUT the jar over the burningcandle, you had all the ingredientsnecessary for combustion; heat from the match, FUEL in the CANDLE and oxygen from the air. ... Remove heat, oxygen or fuel and the FIRE goes out.

V VARIES t I the ANSWER HOPE it HELPS

Because they are HIGH REACTIVE MOLECULES

YEAH , AM PREPARING FOR JEE LEVEL....

THANKS...

I didn't UNDERSTAND what you ASKED in this QUESTION

Nuclear ENERGY ORIGINATES from the splitting of uranium atom, a process called fission .
this generates heat to PRODUCED steam which is used by a TURBINE generator to generate electricity.
Because Nuclear Power Plant do not burn fuel .
they do not PRODUCE greenhouse gas emission

Hope it will help you ✌✌

It's TRUE but can't be USED for ELECTROPLATING

Hiii DEAR here is your answer


Pressure WELDING is a process in which external pressure is applied to producewelded joints either at temperatures below the melting point, which is solid state welding, or at a TEMPERATURE above the melting point, which is fusion state welding. ... Percussionwelding is utilized for JOINING DISSIMILAR metals.


Hope it's help u

The THIRD POSSIBLE arrangement for carbon is sp HYBRIDIZATION which occurs when carbon is bound to two other atoms (two double bonds or one single + one triple bond). This hybridization results in a linear arrangement with an ANGLE of 180° between bonds.

Welding is the process by which two pieces of metal can be joined together. The process of welding doesn't merely bond the two pieces together as in brazing and soldering, but, through the USE of extreme heat and SOMETIMES the addition of other metals or gases, CAUSES the metalic structures of the two pieces to join together and become one. There are a number of different welding methods, including spot welding, metal inert gas (MIG), and tungsten inert gas, which are FORMS of gas metal arc welding, arc welding, and gas welding, to name a few. Welding can even be done underwater.

Hii DEAR here is your answer


Motion of a body is ALWAYS determined with the help of a reference point. The CHOSEN reference point is considered to be fixed in ideal notion so that the change in position of a body can be observed. A reference point in motion may also be chosen but in this case the velocity of the body and the reference point MUST not be equal otherwise the change in position of the body cannot be observed.

As we know GOLD is a soft METAL so if we use 24 caret i.e. PURE gold in making JEWELRY then jewelry will be very soft

They are DEFINITELY PURE gold but ABSOLUTELY useless.
It's because of its characteristics. It is too SOFT to USE. In fact 24 carat gold don't show identified properties of metals.
Therefore, they are alloyed with some selected metals to form 22 carat, 20 carat etc.

The THINGS which can be DECOMPOSED by BACTERIA.

The ANSWER is ATMOSPHERE.

ANSWER....

Human Female Reproductive System

it consists of following organ:-

Ovaries - PAIRED ovaries are located in the abdominal cavity NEAR the kidney. ovaries produce female gamete (ovum or egg) and secret female hormone ( estrogen or progesterone). one egg is produce every month ALTERNATELY by one of the ovaries.

Fallopian tube - the egg is carried from the ovary to womb or uterus through thin oviduct or fallopian tube.

Uterus - the two of a ducting unite into an elastic bag like a STRUCTURE known as uterus.

Vagina - uterus opens to vagina. it is female copulatory organ.

THANKS:)

The FEMALE reproductive system is made up of the internal and external sex organs that function in reproduction of new offspring. In the HUMAN the female reproductive system is immature at birth and develops to maturity at puberty to be able to produce gametes, and to carry a fetus to full term. The internal sex organs are the uterus, Fallopian tubes, and ovaries. The uterus or womb accommodates the embryowhich develops into the fetus. The uterus also produces VAGINAL and UTERINE secretions which help the transit of sperm to the Fallopian tubes. The ovaries produce the ova (egg cells). The external sex organs are also known as the GENITALS and these are the organs of the vulva including the labia, clitoris, and vaginal opening. The vagina is connected to the uterus at the cervix.[1

And then it will result in decay as the bacteria will do it's roleplay. Now TOOTHPASTE contains base, which just neutralizes the acids RELEASED by some bacteria AFER decomposition of SWEETS and hence preventing TOOTH decay. When a person has a sweet tooth, they tend to eat foods that are artificially sweetened.

Did you mean NO2?

By the way I am giving the answer for NO2

NITROGEN Dioxide (NO2): Nitrogen Dioxide is one of the OXIDES which can react to produce Ozone, but that is far from its only negative effect. Nitrogen Dioxide is one of the gases that one most commonly thinks to when considering air pollution: thick, brown, and choking, it is one of the more visibly harmful pollutants.

Sources: Nitrogen Dioxide, like many other pollutants, is most often released into the atmosphere by the burning of fossil fuels in car engines, airplane engines, factories, and power plants.

Effects: In addition to being a choking and obstructive gas in the air, Nitrogen Dioxide also has the PROPENSITY to react with other agents to form nitric acid and organic nitrates, contributing to the formation of acid rain.

Needless to say, Nitrogen Oxide has a huge effect on humans, increasing the likelihood of respiratory problems, cancers, and other lung problems. Acid rains produced by Nitrogen Dioxide are extremely harmful to plants and animals ACROSS the world, and can lead to further problems in water systems.

Because of
less JOB opportunities
low level development and modernisation
less infrastructure
high temperature
less rainfall
sandy and mountainous soil
access SPICY FOOD

I would advise him to INCREASE the voltage of the cells and CHANGE the bulb to LED bulb which GIVES out more light and SHINES brightly.

What is EXACT QUESTION FRIEND please SEND CORRECT question☺
